Christoph Ungerer of the Federal Reserve Board finds that expansionary monetary policy can increase household leverage by making lenders more likely to finance a larger share of the house price. This is because when rates are lower, more households enter the market, and the amount of time that a house remains on the market is reduced, lowering the cost of selling a foreclosed-upon house for lenders. This finding demonstrates a possible trade-off for central bankers between price stabilization and financial stability.

Benjamin Hansen of the University of Oregon, Joseph J. Sabia of San Diego State University, and Daniel I. Rees of the University of Colorado Denver find that higher cigarette taxes were associated with lower youth smoking rates between 1991 and 2005, but that this relationship has become nearly non-existent since 2005. The authors speculate that this may be because cigarette taxes were high enough by 2005 that nearly all price-sensitive youths were deterred from smoking, or because an increasing reliance on online vendors has insulated youths from higher cigarette taxes.

… What Greece wants is to remain in the eurozone, with a lower debt burden – a position that is both economically astute and protected by treaty. Indeed, a euro exit would be remarkably costly for Greece, and would almost certainly create political and social chaos – and perhaps even hyperinflation – in the heart of Europe. The value of Greek residents’ savings would be slashed, as euros were suddenly converted into New Drachmas. The middle class would be eviscerated. And the currency conversion would not save the country one cent with regard to its external debt, which would, of course, remain denominated in euros.
